This paper studies small and medium sized financial agency's management states that take advantage of the Korea Federation of Saving Bank's data. It also presents the management state and the decision-making model that monitors progressive insolvency by standardizing transfer path between relevant groups. With this in mind, we extracted explanatory variables for predictions of insolvency by using existing studies of document related insolvency. First of all, we designed a state model based on demarcated groups to take advantage of the self organizing map that groups in line with a neural network. Secondly, we developed a transition model by standardizing the transfer path between individual banks in a state model. Finally, we presented a decision-making model that integrated the state model and the transition model. This paper will provide groundwork for methods of insolvency prevention to businesses in order for them to have a smooth management system in the financial agencies.

This paper proposes a strategic portfolio model for managing performance of online games. The portfolio matrix is composed of two dimensions: financial performance and non-financial performance. Financial performance is measured by the conventional measure, average revenue per user (ARPU). In terms of non-financial performance, five non-financial key performance indicators (KPIs) that have been widely used in the online game industry are utilized: RU (Register User), VU (Visiting User), TS (Time Spent), ACU (Average Current User), MCU (Maximum Current User). Data envelopment analysis (DEA) is then employed to produce a single performance measure aggregating the five KPIs. DEA is a linear programming model for measuring the relative efficiency of decision making unit (DMUs) with multiple inputs and outputs. This study employs DEA as a tool for multiple criteria decision making (MCDM), in particular, the pure output model without inputs. Combining the two types of performance produces the online game portfolio matrix with four quadrants: Dark Horse, Stop Loss, Jack Pot, Luxury Goods. A case study of 39 online games provided by company 'N' is provided. The proposed portfolio model is expected to be fruitfully used for strategic decision making of online game companies.

건축개발사업은 목적물을 완성시킴으로써 이윤을 창출하는 사업이고, 프로젝트의 성공을 좌우하는 것은 프로젝트 초기에 사업타당성을 정확히 분석하고 예측하는 것에 달려있다. 사업타당성 분실은 본질적으로 현재시점에서 미래예측이라는 불확실성을 내포하고 있으므로 불확실한 상황 하에서 의사결정을 할 수밖에 없다. 이러한 불확실성 하에서의 의사결정방법은 통계학의 확률이론에 기초하고 있지만, 지금까지 사업 타당성 분석은 확률론적 결정방법에 의한 타당성 분석이 아니라 결정론적 방법에 의한 타당성분석을 적용하여 왔다. 따라서 본 연구에서는 초기 사업 타당성 분석 시 프로젝트의 성공을 위해 확률론적 방법에 의한 의사결정을 함으로써, 의사결정 자에게 좀 더 정확하고 신뢰성 있는 자료를 제공할 수 있는 시뮬레이션을 이용한 확률론적 분석방법을 제시한다. 본 연구 결과 확률론적 시뮬레이션 기 법은 건축개발사업의 재무적 타당성 분석 기법으로 적합하다. 중요한 사업 또는 신중한 의사결정시 이 방법을 활용함으로서 정확성과 신뢰성에 근거하여 효율적인 판단이 가능해 질 것이므로 그 활용성이 기대된다.

금융회사가 개인정보를 수집하기 위해서는 법률에 정해진 내용을 소비자에게 명시적으로 알리고 사전 동의를 받도록 되어 있다. 그 결과 금융상품이 복잡해지고 다양해짐에 따라 '개인정보제공 동의서' 내용도 복잡해지고 분량이 많아지게 되었다. 특히 인터넷과 모바일의 경우 화면 크기의 제약으로 글씨가 더 작아지면서 더욱 이해하기가 힘들어졌다. 이것은 개인정보를 수집하는 거의 모든 기업이 비슷한 상황이어서, 서비스를 이용하는 소비자 입장에서는 동의 내용을 이해못한 채 습관적으로 동의하는 모순이 생기고 있다. 본 연구에서는 금융회사 인터넷 홈페이지를 통한 합리적인 개인정보 수집 및 이용 동의 정책 수립 모델을 제시하기 위해 국내외 법제도를 고찰하여 문제점을 도출하고 개선 방안을 제시한다. 또 연구를 통해 선정된 평가요인을 AHP(Analytic Hierarchy Process)방법을 이용하여 의사결정 모델과 공식을 제시하고 검증한다.

This research is aimed at examining the effect of the implementation of ABAS and BR on GFP with FDM as mediation. Respondent of research is 100 civil servants at the Directorate General of Population and Civil Registration of the Ministry of Home Affairs for the Republic of Indonesia. Data analysis is done with WarpPLS. Result of research shows that the implementation of ABAS has direct and indirect effects on GFP, and the indirect effect involves the mediation of FDM. Other result indicate that the making of proper financial decisions will help improving GFP. The effectiveness of financial decisions are able to mediate the implementation of ABAS in improve GFP. Meanwhile, BR does not affect GFP, either directly or indirectly through FDM. BR seems oriented more toward improving public service and people's welfare. This research suggests that the next research should examine whether the implementation of BR can improve governmental organizational performance in delivering public service. This research has proven that the implementation of ABAS has helped in improving the quality of FDM, while the other benefit is that this system improves GFP. Moreover, this research also gives confirmation that accounting information in good quality will be very useful in FDM.

본 연구의 목적은 화이트칼라 범죄의 의사결정 과정에 영향을 미치는 요인들이 무엇인지 살펴보고, 이 요인들의 유무에 따라서 의사결정의 합리성 정도에 차이가 나타나는지 실험을 통해 확인하고자 함이다. 본 연구의 실험은 피험자 간 설계로 재정적 압박 지시 유무와 Tit for tat 전략 정보 제공 유무에 따라서 조건별로 할당하였다. 실험 참가자들은 화이트칼라 직군에 근무하는 성인 102명으로, 화이트칼라 범죄 시나리오로 각색한 변형된 연속되는 죄수의 딜레마 상황에서 의사결정을 진행하고 이에 따른 점수를 획득하는 과정을 거쳤다. 획득 점수는 범죄를 저지를 위험성을 나타내며, 점수가 낮을수록 범죄에 참여할 위험성이 높음을 의미하였다. 연구 결과는 재정적 압박 지시 없이 전략 정보만 제공받은 집단이 범죄에 참여할 위험성이 가장 낮았으며, 재정적 압박 지시만 받고 전략 정보를 제공받지 않은 집단의 범죄 참여 위험성이 가장 높았다. 또, 재정적 압박 지시를 받은 집단은 전략 정보 제공과 관계없이 재정적 압박 지시를 받지 않은 집단보다 범죄 참여 위험성이 높았으나, 전략 정보를 제공받은 집단 중 재정적 압박 지시를 함께 받은 집단은 재정적 압박 지시와 전략 정보 제공을 둘 다 받지 않은 집단보다 범죄 참여 위험성이 높았다. 연구 결과를 바탕으로 본 연구는 재정적 압박을 합법적으로 해소할 수 있는 방안의 필요성과 직장인을 대상으로 한 화이트칼라 범죄에 대한 교육의 필요성, 기업 내에서 독단적이지 않고 협력적이며 상호검증 가능한 의사결정 구조의 필요성을 제안하였다.

Purpose The study aims to develop a data-based decision model for private bankers when recommending hedge funds to their customers in financial institutions. Design/methodology/approach The independent variables are set in two groups. The independent variables of the first group are aggressive investors, active investors, and risk-neutral type investors. In the second group, variables considered by private bankers include customer propensity to invest, reliability, product subscription experience, professionalism, intimacy, and product understanding. A decision-making variable for a private banker is in recommending a first-rate general private fund composed of foreign and domestic FinTech products. These contain dependent variables that include target return rate(%), fund period (months), safeguard existence, underlying asset, and hedge fund name. Findings Based on the research results, there is a 94.4% accuracy in decision-making when the independent variables (customer rating, reliability, intimacy, product subscription experience, professionalism and product understanding) are used according to the following order of relevant dependent variables: step 1 on safeguard existence, step 2 on target return rate, step 3 on fund period, and step 4 on hedge fund name. Next, a 93.7% accuracy is expected when decision-making uses the following order of dependent variables: step 1 on safeguard existence, step 2 on target return rate, step 3 on underlying asset, and step 4 on fund period. In conclusion, a private banker conducts a decision making stage when recommending hedge funds to their customers. When examining a private banker's recommendations of hedge funds to a customer, independent variables influencing dependent variables are intimacy, product comprehension, and product subscription experience according to a categorical regression model and artificial neural network analysis model.

Regarding all methods of decision making as parts of the same subject, one is astounded to find that the field speaks to the practitioners about multicriteria decision making with a multi-forked tongue, different methods give different and conflicting outcomes even for very simple decisions. In this paper, five well-known decision theories are described and used to work out a simple decision to choose the best of three cars. The outcomes turn out not to be the same for all the methods, which is troubling because one would expect unique answers in decision making. Several "meta" criteria that are essential for making a decision theory to make a choice as to which decision approach is best.h is best.

This paper presents a fuzzy-goal programming(FGP) approach for Bi-Level Linear Multiple Objective Decision Making(BLL-MODM) problem in a large hierarchical decision making and planning organization. The proposed approach combines the attractive features of both fuzzy set theory and goal programming(GP) for MODM problem. The GP problem has been developed by fixing the weights and aspiration levels for generating pareto-optimal(satisfactory) solution at each level for BLL-MODM problem. The higher level decision maker(HLDM) provides the preferred values of decision vector under his control and bounds of his objective function to direct the lower level decision maker(LLDM) to search for his solution in the right direction. Illustrative numerical example is provided to demonstrate the proposed approach.

Nowadays, using math logic in great civil projects is considered by the clients to achieve the goals of project including quality optimization, costs, avoiding individual, emotional and political decision making, long-term and short-term goals and they are the main requirements of each project and should be considered by the decision makers to avoid the illogical decision making applied on the majority of civil projects and this imposes great financial and spiritual costs on our country. The present study attempts to present one of the civil projects (Ghasre Shirin storage dam) whose client was not ministry of energy for the first time and the short-term and long-term goals of the private sector were applied based on the triangle of quality, cost and time. Also, the math logic and model (multi-criteria decision making method and decision making matrix) is used in one of the most important sections of project, sealing element, policies and new materials (Geosynthetics) are considered and this leads to suitable decision making in this regard. It is worth to mention that this method is used for other sections of a dam including body, water diversion system, diaphragm and other sectors or in other civil projects of building, road construction, etc.
